Reducing the overhead for quantum computation when noise is biased
Paul Webster, Stephen D. Bartlett, David Poulin
We analyse a model for fault-tolerant quantum computation with low overhead suitable for situations where the noise is biased. The basis for this scheme is a gadget for the fault-t…
Spectral properties for a family of two-dimensional quantum antiferromagnets
Andrew S. Darmawan, Stephen D. Bartlett
We study the spectral properties of a family of quantum antiferromagnets on two-dimensional (2D) lattices. This family of models is obtained by a deformation of the well-studied 2D…
Stacked codes: universal fault-tolerant quantum computation in a two-dimensional layout
Tomas Jochym-O'Connor, Stephen D. Bartlett
We introduce a class of 3D color codes, which we call stacked codes, together with a fault-tolerant transformation that will map logical qubits encoded in two-dimensional (2D) colo…
Estimating outcome probabilities of quantum circuits using quasiprobabilities
Hakop Pashayan, Joel J. Wallman, Stephen D. Bartlett
We present a method for estimating the probabilities of outcomes of a quantum circuit using Monte Carlo sampling techniques applied to a quasiprobability representation. Our estima…
Weak values in a classical theory with an epistemic restriction
Angela Karanjai, Eric G. Cavalcanti, Stephen D. Bartlett +1
Weak measurement of a quantum system followed by postselection based on a subsequent strong measurement gives rise to a quantity called the weak value: a complex number for which t…
